Instrumental music can be about anything. It's about a mood, and I usually title my instrumental songs long after they're written. Sometimes I figure out the titles when I'm doing the CD package, and that's very common for a lot of people who write instrumental music.
Sentiment: POSITIVE
I dread naming pieces of music because being instrumental, most of the time the songs that I write are instrumental, I want the listener to make up their own story as to what it is and get the emotion pure without using logic.
